THE PRELIMINARY RESEARCH ON AERIAL MULTISPECTRAL REMOTE SENSING OF WATER DEPTH

Second Institute of Oceanography, National Bureau of Oceanography, Hangzhou

摘要

摘要: 为了探讨在我国目前条件下利用航空多光谱摄影手段遥感水深的可能和方法,在1978年10月至1979年10月的约一年时间里,国家海洋局第二海洋研究所遥感技术研究室先后在我国云南保山地区、吉林长春地区以及东海三大王海湾进行了三次水深航空多光谱摄影的遥感试验研究.本论文试图根据这三次试验的实践,阐述利用航空多光谱摄影遥感水深的原理和方法,估价在我国目前条件下所能达到的限度,讨论今后的研究方向和改进办法.

Abstract: Starting from the three tests of aerial multispectral sensing at the Dahaizi reservoir,reservoirs near Changchun district and Sandawang Bay,the authors explain systematically in this paper the basic principle and the method of remote sensing for determine water depth using aerial multispectral photography.On the basis of basic principles of geometric,physical and water optics,and foreign data,we propose a depth equation with the effect of forward scattering on light radiation transmission considered,expound the specific physical significance of various parameters in the equation,and establish the respective method of measurement or Pstimation.According to the remote sensing instruments aid equipment of our country,we mainly demonstrate each major step and concrete method associated with the determination of water depth by the single spectral channel ratio technique in aerial remote sensing,fox' example,the selection of best waveband,the flying conditions and the requirements for image processing,and so on.
